Exactly! The rocket engines of these missiles only work for few seconds to bring them to their top speeds. Then they travel with their kinetic energy. As they are moving without thrust they are being effected by gravity. So can be deemed to have a “ballistic” trajectory.
But a throttle controlled Ramjet, has thrust till the last second.
I been following some of this convo, but I do not know the underlying context etc...so I am probably overthinking lot of this, but just for sake of reaching more complete possibilities....
It did occur to me (if we do not know context of how "ballistic" is exactly applied to such ramjet system in first place) there are some possibilities/scopes on top of the one given by "The Insider" (as generic word for propulsive test etc).
A) Ramjet-stop and restart (later in course) at a lower but still high enough mach speed. The profile during this phase would essentially be a ballistic trajectory. i.e ramjet pulse system effectively.
B) Ramjet-stop and later start of different propulsive method of the larger system (say a final rocket phase etc). Similar to the above, just different systematic pulses involves. Again there would be a ballistic "coast" involved between the pulses.
C) A ballistic test (for sake of argument) could also mean a rocket launches the ramjet test-module initially from the ground (with a ballistic trajectory to obtain the necessary velocity for ramjet testing). This is essentially what India's recent SFDR tests involved (i.e a booster rocket rather than aerial platform....latter likely will be a later test for more mature system downstream).
